Transportowy Dozor Techniczny

What Transportowy Dozor Techniczny does

Transportowy Dozór Techniczny (TDT) is a Polish state legal entity (państwowa osoba prawna) established on December 21, 2000 through the merger of Kolejowy Dozór Techniczny and Dozór Techniczny Żeglugi Morskiej, and subordinate to the Minister of Transport. It is the sole national technical supervision authority for rail, road dangerous goods, maritime, inland waterway, rope transport, and pressure equipment in Poland, operating as Notified Body 1468 for EU conformity assessment under directives including 2010/35/UE, 2014/68/UE, 2016/797, and 2016/424.

The organization's core products are regulatory rather than commercial: periodic and post-accident technical inspections, vehicle and equipment type approvals (EU and UN), conformity assessments for products/management systems/personnel, ADR/DGSA/ADN qualification certifications, and market surveillance. Its technical backbone is the TDT Laboratory in Kraków (PCA AB 1141), equipped for non-destructive testing (VT, PT, MT, UT, UT-PA, ToFD, RT, MRT, AT, ET) plus chemical composition analysis (ARL 3460 OES), mechanical testing up to 600 kN, and acoustic emission, supported by five PCA accreditations. Service delivery is organized through 9 regional territorial offices and 6 inspector teams covering all Polish voivodeships, the Kraków laboratory, the e-TDT electronic platform, and a centralized helpline.

Revenue is generated through statutory fees for supervisory and certification activities (e.g., 333.88 PLN qualification examination fee, fixed conformity-assessment fees), paid laboratory testing services, certification product revenue, and direct government budget allocation. The entity is not commercially marketed; customer acquisition is statutory-mandated rather than sales-driven. TDT also operates the Akademia TDT training center and supervises alternative-fuel infrastructure including hydrogen refueling stations.
